IERCOLATOR.

Specification of Letters Patent.

Patented May 31, 1910.

Application filed February 4, 1910. Serial No. 542,161.

. citizen of the United States, residing at \Vashington, in .the District of Columbia,

have invented certain new and useful Improvements in Percolators, of which the following is a specification, reference being had therein to the accompanying drawing.

My present invention relates to improvements in percolators, and more especially designed for use in connection with the ordinary form of coflee or tea pot, whereby they are readily and quickly transformed into a percolator, which will properly secure the aroma from the ground coffee, without the attendant feature of grounds, and the necessity of employin egg-shells and cold water to settle or clarify the drink.

This percolator attachment, is made with the heating chamber adapted to enter the top opening of the ordinary pot and rest upon the bottom, the fountain tube leading upwardly therefrom being vertically and slidably adjustable to fit various heights of pots and at the same time, insure the heating chamber resting upon the center of the bottom. The basket is made preferably of a piece of cloth or screen, which is held in place by a supportslidably and removably mounted upon the upper end of the fountain tube, while carried by the said support is also the glass cover or dome, against which the boiling liquid is projected and conducted back upon a perforated spreader also carried by the support. (Jo-acting with the support to secure the cloth or screen securely in place is a tapered band which corresponds to the tapered band of the support, while carried by this band is a wire handle or bail, which engages the top of the cover or dome, and by the action thereagainst clamps the cover in place and simultaneously clamps the cloth or screen immovably between the support and tapered band, and between the support and fountain tube, whereby the basket cover and fountain tube with the heating chamber, may be bodily removed from the pot, when desired.

To clearly demonstrate the advantages of my percolator, attention is invited to the accompanying drawings, in which Figure 1 is a vertical central sectional view through my percolator and the pot, carrying the same. Fig. 2 is a perspective ment.

Fig. 10 is a top plan view thereof.

Referring to the drawings :The unmeral 1 designates the pot, which is provided with the usual cover 2.

My percolator, comprises the concaved heating chamber 3, which is circular and of a suflicient size or diameter to easily pass through the top opening of the pot, and have its lower edge resting upon the bottom of the pot, the lower edge being provided with the series of notches, recesses or apertures 4, whereby the liquid is permitted to enter the chamber, and the lower fountain tube or section 5, which projects centrally upward from the chamber, and thus conveys the heated or boiling liquid to the top of the percolator through the upper section 6, of the fountain tube, thus with the section 5, forming a telescoping or adjustable fountain tube, whereby pots of various heights may be employed with my percolator and not necessitate the construction of a special pot therefor.

Secured rigidly to the section 6, near its lower end is a flange or disk 7, which with the flange or disk 8, carried upon the lower end of the tube or sleeve 9, co-act to grip the central portion a, of the cloth or screen basket 10, in place. Carried by the upper end of the sleeve 9, is a spider 11, which secures the tapered band or basket support 12, to the sleeve 9, thus permitting the sleeve to carry said band and the-disk 8 bodily therewith, the said sleeve being removably mounted upon the upper end of the tube 6 andbein limited in its downward movement by the isk 7.

Adapted to fit within the mouth of the pot is the co-acting clamping tapered band 13, between which and the band 12 fits and is clamped the upper edge 6, of the cloth or screen, the said band 13, being provided with 7 and 8, and the edge 6, between the bands 12 and 13, the said bail handle in this position permitting the percolator to be bodily lifted by the said bail handle to place the percolator in the pot or remove it therefrom. The knob 17 of the cover or dome is provided with the grooves ve, for the reception of the central portion of the bail.

Removably mounted over the upper end of the section 6 of the fountain tube and resting upon the band 12, is a spreader 18, which is provided with the series of concentric grooves 19, providing the perforations 20, whereby liquid sprayed through the opening 21, in the top of the fountain tube will be projected against the dome, and upon the spreader whose grooves and perforations spread the liquid and feed it upon the substance within the basket.

In Fig. 7, the bail handle 22, is provided with the spring connection 23, at each junction with the lug 24, of the band 13, this permitting a more easy action in clamping the cover or dome in place.

In the modified form illustrated in Figs.

' 8, 9 and 10, I deviate slightly from the construction described, in that the tapered band 12, which corresponds to the band 12, carries the series of strips 25, which conform and in reality form the shape of the bag or basket 26, which is exterior thereof and is held in place by the bail carrying and clamping band 13", and the central disk 27, and disk 28 carried by the fountain tube 28. The upper edge of the band 12', is provided with the two rims 29 and 30, the rim 29, of which forms a seat for the lower edge of the cover or dome 31, while the rim 30, forms a seat for the perforated spreader 32, which fits over the upper end of the fountain tube and assists in holding the band 12 in place or centered. The handle 33, has its ends 34 secured to th lugs 35, of the band 13, and is provided with the knob engaging central portil n 36 and the coiled grips 37, which provide a practically selfcoolmg grip for the fingers of the party removing the percolator, and insures against the burning thereof.

The sleeve 9 at its junction with the disk 8, is provided with the bayonet slot 38, which co-acts with the studs 39 carried by the section 6 of the fountain tube, thus providing a means whereby the fountain tube and heating chamber are connected bodily to the sleeve 9, and thereby insuring the movement of the same with the complete percolator. The disk 27 is provided with the oppositely arranged slots 39, which coact w1th the studs 40, of the fountain tube 28, for the same reason.

From the foregoing description, it will be seen that by makin the two bands which fit in the mouth of t e pot tapering, that pots of various diameters, varying from the smallest diameter of the outer band to the extreme diameter at the top of the band, may be used; and that by making the fountain tube telescoping pots of various heights may be accommodated. I have found that when inserting the percolator, it is best to pull the tubes to almost their extreme extension, for when the heating chamber is seated upon the bottom of the pot, the basket may be pushed down until the outer band snugly fits within the mouth of the pot. By this means the proper working of the percolator is assured.

In making these percolator attachments, I propose to make them in various sizes, as for instance for one quart, two quart, three quart and four quart pots.

What I claim, as new, is :-,v

1. In a percolator, the combination of a heating chamber, a fountain tube, a drip basket, a cover for the basket, and means carried by the basket and accessible from the exterior of the basket and cover for clamping the cover to the basket and forming a means whereby the percolator may be bodily lifted by said means.
